RESUMO

RATIONALE: Amid the pervasive deployment of imidacloprid, the incidence of poisoning from this compound has risen markedly. Those afflicted with imidacloprid poisoning typically exhibit symptoms ranging from headaches, dizziness, nausea, and abdominal pain, to impaired consciousness and breathlessness, yet instances of ocular paralysis induced by this toxin have not previously been documented. PATIENT CONCERNS: When the pesticide spray inadvertently made contact with the patient's eyes, they were seared with a burning sensation and discomfort. Subsequent to this incident, on the second day, the individual began to experience diplopia in the right eye and found it arduous to elevate his eyelids, indicating a challenge in achieving full extension. DIAGNOSES: Based on the medical history, symptoms, and signs, the patient was diagnosed with oculomotor nerve palsy caused by imidacloprid. INTERVENTIONS: The treatment involved intravenous dexamethasone to reduce inflammatory response in the eye tissue; oral pantoprazole enteric-coated tablets to suppress acid production and protect the stomach; Xuesaitong administered intravenously to improve blood supply to the eye and promote metabolism of toxins; vitamin C, cobamamide, and vitamin B1 for nerve nutrition and antioxidant effects; local application of tobramycin-dexamethasone eye drops for anti-inflammatory purposes; and repeated flushing of the conjunctival sac with saline. Finally, the patient improved and was discharged. OUTCOMES: After active treatment, the patient finally improved diplopia and ptosis. LESSONS: This report marks the first documentation of oculomotor nerve palsy induced by imidacloprid, featuring diplopia, and blepharoptosis without substantial limitation of ocular motility. Following therapeutic intervention, the patient showed marked improvement and was discharged from the hospital, providing a point of reference for the treatment of analogous cases in future clinical practice. It also serves as a reminder for the public to take appropriate precautions when using imidacloprid.

RESUMO

Purpose: To study the clinical spectrum and recovery patterns in patients of acquired isolated ocular motor nerve palsies (OMNPs). Methods: Patients above 5 years of age with various etiologies of OMNPs were included. Demographic and ocular details were recorded, and a squint assessment was performed. Recovery patterns at 3 and 6 months were noted. Results: OMNP was more common in adults, in the order VI > III > IV nerve. Ischemic cause (35%) was followed by idiopathic (26.3%). III nerve palsies were all unilateral, of which all ischemic palsies were pupil-sparing. By 6 months, >50 patients showing complete recovery had ischemic and idiopathic palsies. Smaller baseline deviation correlated with better recovery. Conclusion: Acquired isolated OMNPs are mostly ischemia-related, with >80% of cases fully recovering by 6 months. VI nerve palsy of ischemic or idiopathic etiology and small baseline deviation were associated with self-recovery.

RESUMO

INTRODUCTION: Oculomotor nerve palsy (ONP) is often discovered in the ophthalmology department, manifested as ptosis with the same side, eyeball in the fixed external booth, or accompanied by limited inward, upward, and downward movements. The present case report described the effect of electroacupuncture (EA) on a breast cancer patient with ONP after chemotherapy. PATIENT CONCERNS: A 56-year-old breast cancer patient presented with severe ptosis and fixed right eye exotropia. Besides, it is challenging to perform the movement inward, upward, and downward, and with obvious diplopia. DIAGNOSES: The breast cancer patient was diagnosed with ONP, chemotherapy history. INTERVENTIONS: The patient was introduced to acupuncture department to receiving EA treatment. OUTCOMES: After 12 times of EA treatments, the symptom of ptosis was significantly improved, and the right upper eyelid can lift autonomously as same as the left eye. Besides, the patient's right lateral eye could move freely, and the symptoms of double vision disappeared. CONCLUSION: The case suggests that EA may be an effective alternative treatment for ONP.

RESUMO

BACKGROUND: This cohort study aims to examine the relationship between the occurrence of cranial nerve palsy (CNP) affecting the third, fourth, or sixth cranial nerve and the subsequent risk of stroke, with a particular focus on the modulating effect of age on this association. METHODS AND RESULTS: We established a cohort of individuals diagnosed with third, fourth, or sixth CNP who underwent national health screening within 2 years of diagnosis from 2010 to 2017. A control group was matched by sex and age at a ratio of 1:5. Participants were followed until December 31, 2019. We use multivariable Cox proportional hazards regression analyses to assess the association between ocular motor CNP and subsequent stroke stratified by age. Covariates including lifestyle, health behavior, underlying comorbidities, and Charlson comorbidity index score were also adjusted. Compared with the control group, the ocular motor CNP group had a higher risk of stroke after adjusting for potential confounders (hazard ratio [HR], 1.23 [95% CI,, 1.08-1.39]). The risk of stroke increased by 8.91 times in individuals with ocular motor CNP who were in their 30s (HR, 8.91 [95% CI, 1.63-48.66]). The risk increased by 2.49 times in those who were in their 40s, 1.78 times in those who were in their 50s, and 1.32 times in those who were in their 60s (HRs, 2.49, 1.78, and 1.32 [95% CI, 1.39-4.45, 1.31-2.42, and 1.08-1.62], respectively). However, for those who were in their 20s, 70s, or 80s, the incidence of stroke did not significantly increase. CONCLUSIONS: Our study establishes an association between ocular motor CNP and an increased risk of stroke, particularly in young adults.

RESUMO

Understanding the association between dipstick-detected proteinuria and oculomotor cranial nerve palsy (CNP) could have significant implications for understanding the mechanism of CNP development and for developing preventive strategies against CNP development in patients with proteinuria. This study aimed to determine the relationship between dipstick-determined proteinuria and ocular motor CNP using National Sample Cohort (NSC) database from Korea's National Health Insurance Service (NHIS). A nationwide population-based cohort study was conducted using data from the NSC database of Korea's NHIS. These data were collected from 2009 to 2018. A one-year time lag was established to prevent a situation in which the causal link was inverted. Participants aged 20 years or more who were diagnosed with proteinuria in 2009 were included. Individuals with specific pre-existing CNP, missing data, and those who were newly diagnosed with CNP or who died within one year of being tested were excluded. The study population was classified into six groups according to the degree of proteinuria (negative, trace, or between 1 + and 4 +) based on the urine dipstick test. A Cox proportional hazard regression analysis was performed to determine the linkage between the degree of proteinuria and ocular motor CNP. A total of 5,807 (0.14% of subjects) with ocular motor CNP were assigned to the ocular motor CNP group and 4,047,205 subjects were assigned to the control group. After full adjustment of comorbidities, hazard ratios (HRs) for 1 + , 2 + , 3 + and 4 + proteinuria groups were 1.449 (95% confidence interval [CI] 1.244-1.687), 2.081 (1.707-2.538), 1.96 (1.322-2.904), and 3.011 (1.507-6.014), respectively, for developing ocular motor CNP compared to the proteinuria-negative group. In subgroup analysis, the HR of patients with proteinuria for the development of ocular motor CNP was higher in the younger age group (less than 40 years) (P = 0.0242) and the group with DM (P = 0.04). Our population-based cohort study demonstrated a significant association between proteinuria and the incidence of CNP, suggesting that urine protein level could be a new clinical marker for predicting the development of CNP.

RESUMO

OBJECTIVE: Unruptured posterior communicating artery (Pcom) aneurysms cause oculomotor nerve palsy (ONP). However, the time course of recovery after aneurysm repair remains unclear. We aimed to evaluate the ONP course after clipping and coiling for unruptured Pcom aneurysms. METHODS: We retrospectively reviewed the medical records of 25 consecutive patients with ONP due to unruptured Pcom aneurysms, undergoing aneurysm repair at our institution during 2010-2022. We analyzed the clinical data, angiographic results, and surgical complications. The time to ONP recovery was evaluated using the Kaplan-Meier method. RESULTS: This study included 14 patients undergoing surgical clipping and 11 undergoing endovascular coiling. The two groups exhibited no significant differences in complete or partial ONP percentage or in symptom presentation (ptosis, diplopia, ocular paralysis, pupillary light reflex disorder, or mydriasis). All patients achieved complete or partial recovery during the follow-up period. The median time to partial or complete improvement in ONP was significantly shorter for clipping compared to coiling (2 days vs. 33 days; P = 0.009). Preoperative partial and complete ONP were stratified; clipping improved significantly earlier than coiling in the complete ONP group (P = 0.010). In the early treatment group (based on the median duration of treatment), clipping resulted in earlier improvement than coiling (P = 0.014). In the small aneurysm group (based on the median of the aneurysm maximum diameter), clipping resulted in earlier improvement than coiling (P = 0.005). CONCLUSION: In ONP caused by an unruptured Pcom aneurysm, clipping may provide faster recovery than coiling, particularly in cases of early onset, complete palsy, and small aneurysms.

RESUMO

BACKGROUND Symptoms caused by developmental venous anomalies (DVAs) are usually mild and unspecific. Despite the benign nature of DVAs, they can occasionally be symptomatic. CASE REPORT A 67-year-old woman presented with sudden diplopia and left eyelid ptosis for 10 days. A neurologic examination revealed left complete oculomotor nerve palsy. Other neurologic deficits, including eye pain or pulsatile tinnitus, were not detected. Furthermore, the visual acuity was normal. Additionally, no retinal hemorrhage, venous dilatation, or fundus tortuosity were observed. No ischemia lesions or neoplasms were observed in MRI, and no widening or enhancement of the cavernous sinus was detected in post-contrast T1-weighted images, but magnetic resonance tomography cerebral angiography (MRTA) detected an offending vessel compressing the left oculomotor nerve in the fossa interpeduncular. We hypothesized that oculomotor nerve palsy (ONP) was caused by an abnormal arterial structure. However, digital subtraction angiography (DSA) revealed no aneurysm or abnormal arterial structure in the arterial phase, while a tortuous and dilated collecting vein was detected in the venous phase, connecting the left temporal lobe to the left cavernous sinus. This indicated a typical caput medusae appearance, suggesting the mechanism of oculomotor palsy caused by compressive impairment of the DVA. The patient refused microvascular decompression surgery, and ONP persisted after 30 days. Management was conservative, with spontaneous resolution at 60 days and no recurrence during the 2-year follow-up. CONCLUSIONS ONP is rarely caused by DVAs, which are easily ignored due to their benign nature. Cerebral vein examinations are advised for patients exhibiting clinical symptoms of unknown etiology.

RESUMO

PURPOSE: To investigate the effect of endovascular embolization of posterior communicating artery (Pcom) aneurysms on concomitant oculomotor nerve palsy (OMNP) and factors affecting the effect of treatment. MATERIALS AND METHODS: Patients with the Pcom aneurysms concomitant with OMNP were retrospectively enrolled for endovascular treatment of the aneurysms. All patients had the endovascular management. The clinical effect, degree of OMNP, size of the aneurysm, type of treatment, subarachnoid hemorrhage (SAH), and time from onset to treatment were analyzed on the resolution of OMNP. RESULTS: Ninety-six patients with 99 Pcom aneurysms were enrolled and treated endovascularly, with the success rate of 100%. Immediately after endovascular treatment, 75 aneurysms (75.75%) got complete occlusion, and 24 (24.24%) nearly complete occlusion. Followed up for 3-18 (mean 8.52±0.56) months, complete resolution of the OMNP was achieved in 63 patients (65.63%), partial resolution in 21 (21.88%), and non-recovery in the other 12 (12.50%). The degree of OMNP at onset, SAH, and time from onset to treatment were significantly (P<0.05) correlated with the resolution of OMNP. Univariate analysis revealed that younger age of the patient, degree of OMNP at onset, presence of subarachnoid hemorrhage, and time from disease onset to treatment were significantly (P<0.05) associated with the recovery of OMNP. Multivariate analysis revealed that the younger age, degree of OMNP at onset, and time from disease onset to treatment were significantly (P<0.05) associated with the recovery of OMNP. CONCLUSION: Endovascular embolization of Pcom aneurysms concomitant with OMNP can effectively improve the OMNP symptoms, especially for patients with moderate and a shorter history of OMNP. Younger age, degree of oculomotor nerve palsy at onset, and time from onset to treatment may significantly affect recovery of oculomotor nerve palsy.

RESUMO

BACKGROUND: Isolated ischemic oculomotor nerve palsy as a type of ophthalmic disease is rarely observed in clinical practice. Quality of life is frequently impacted by isolated ischemic oculomotor nerve palsy due to its lack of treatment options and long-term visual impairment. We describe an acupuncture-treated instance of isolated ischemic oculomotor paralysis. METHODS: Acupoints including Jingming (BL 1), Chengqi (ST 1), Cuanzhu (BL 2), and Sizhukong (TE 23) on the right side, and bilateral Fengchi (GB 20), Waiguan (TE 5), Hegu (LI 4), and Zulinqi (GB 41) were selected for needling. Each treatment lasted for 30 minutes, once every other day. Acupuncture treatment was administered for a total of 11 times. RESULTS: Acupuncture is a promising treatment option for isolated ischemic oculomotor nerve palsy. CONCLUSIONS: Ischemic oculomotor nerve paralysis can affect the quality of life of patients. Acupuncture intervention can promote the recovery of the disease is a very effective treatment measure.

RESUMO

Aberrant regeneration occurs in forms of oculomotor motor nerve palsy and frequently involves the pupil, but the incidence and functional impact of ciliary muscle involvement in pediatric patients is sparsely reported in the literature. A 4-year-old girl presented with inflammatory oculomotor motor nerve paresis affecting the inferior division. Initial treatment focused on her inability to accommodate through her physiologic +2.5 D hyperopia and the prevention and treatment of amblyopia. She subsequently developed aberrant regeneration of the pupil, with miosis on adduction. Following eye muscle surgery for residual exotropia and hypertropia, her dry refraction was noted to be more myopic in the affected eye on adduction, mirroring aberrant pupillary constriction. Recognition of pediatric aberrant regeneration of accommodation may influence surgical planning for oculomotor nerve palsy and/or management of amblyopia.

RESUMO

PURPOSE: To analyze and compare the outcome of two different surgical procedures in patients with complete oculomotor nerve palsy with large-angle exotropia. METHODS: The medical records of patients with total oculomotor nerve palsy and large-angle exotropia operated on at a single center from January 2006 to June 2020 were reviewed retrospectively. One group underwent lateral rectus deactivation with medial rectus resection (resection group); the other group underwent lateral rectus deactivation with medial rectus fixation to the medial palpebral ligament (fixation group). Surgical outcomes on the first postoperative day and at 6 months postoperatively were analyzed, including alignment and postoperative complications. All statistical analyses were performed using STATA version 14. A P value of <0.05 was considered significant. RESULTS: A total of 35 patients were included. There was a trend toward greater surgical success in the fixation group (93%) than in the resection group (65%), but these results were not statistically significant. Postoperative exotropic drifts were noted in both the procedures but tended to be more with patients in the resection group. Postoperative complications were noted only in the fixation group. CONCLUSIONS: Lateral rectus deactivation with medial rectus fixation to the medial palpebral ligament requires more time and greater surgical expertise but appears to better prevent postoperative exotropic drift compared with lateral rectus deactivation combined with medial rectus resection.

RESUMO

Oculomotor nerve schwannoma in children not associated with neurofibromatosis is a rare disease, with 26 pediatric cases reported so far. There is no established treatment plan. A 7-year-old girl presented with oculomotor nerve palsy. Surgical reduction of the tumor combined with postoperative gamma knife surgery preserved the oculomotor nerve, improved oculomotor nerve function, and achieved tumor control during the observation period of 20 months. The combination of partial surgical resection and gamma knife surgery as a treatment strategy for oculomotor nerve schwannoma resulted in a good outcome.

RESUMO

BACKGROUND AND PURPOSE: The etiological distribution of oculomotor nerve palsy has varied amongst the studies. This study aimed to define the clinical features and underlying etiologies of isolated oculomotor nerve palsy by recruiting patients from all departments in a referral-based university hospital. METHODS: The medical records of 672 patients who had a confirmed diagnosis of isolated oculomotor nerve palsy at all departments of Seoul National University Bundang Hospital, Seongnam, South Korea, from 2003 to 2020 were reviewed. A proportion of the etiology of isolated oculomotor nerve palsy was also compared with that of patients pooled from the previous studies that were searched on PubMed in May 2022. RESULTS: The most common etiology was microvascular (n = 168, 26.5%), followed by vascular anomalies (n = 110, 17.4%), neoplastic (n = 86, 13.6%), inflammatory (n = 79, 12.5%), idiopathic (n = 60, 9.5%) and traumatic (n = 53, 8.4%). Neurologists were mainly involved in the management of microvascular and inflammatory oculomotor nerve palsies whilst ophthalmologists mainly participated in the care of idiopathic, neoplastic and traumatic palsies. Neurosurgeons mostly took care of oculomotor nerve palsy due to vascular anomalies. CONCLUSIONS: The proportion of etiologies of isolated oculomotor nerve palsy may differ according to the specialties involved in the management. The results of previous studies on the etiological distribution of isolated oculomotor nerve palsy should be interpreted with this consideration.

RESUMO

BACKGROUND: Cavernous malformations (CMs) are clusters of thin-walled sinusoidal vessels without well-defined walls. Though they can occur anywhere in the neuroaxis, cranial nerve (CN) CMs are rare. METHOD: We report a 47-year-old male with gradual CN III palsy. Initial imaging showed no significant findings, but a follow-up MRI revealed a growing lesion along CN III. Intraoperative findings confirmed a CN III CM. Diagnosing and treating CN III CM are complex. Radiological findings lack specificity, requiring consideration of various diagnoses for patients with isolated CN III palsy and abnormal radiological findings. CONCLUSION: Surgery is the gold standard, aiming for complete lesion removal while minimizing neurological complications.
